Can DDR5 server memory deliver as promised? Micron shares our real-world test results.
Anticipation has been high for the arrival of DDR5 server DRAM and the big performance gains it has promised. To validate breakthrough performance with 4th Gen AMD EPYC™ Processors, Micron’s Data Center Workload Engineering team compared DDR4 versus DDR5 server memory running on the appropriate generations of AMD EPYC servers to isolate (to the extent possible) the DDR5 DRAM contribution to the workloads. Three representative workload groups were tested that model typical performance challenges for high performance computing (HPC) applications. These real-world results indicate that with DDR5 memory, individual HPC applications could perform an average of 2x faster.
